A smart airport automation system gathers and reinterprets a wide variety of aircraft and airport related data and information around unattended or non-towered airports. Data is gathered from many different types of sources, and in otherwise incompatible data formats. The smart airport automation system then decodes, assembles, fuses, and broadcasts structured information, in real-time, to aircraft pilots. The fused information is also useful to remotely located air traffic controllers who monitor non-towered airport operations. The system includes a data fusion and distribution computer that imports aircraft position and velocity, weather, and airport specific data. The data inputs are used to compute safe takeoff and landing sequences, and other airport advisory information for participating aircraft.
